What people are saying

Rated 5 out of 5 by from Awesome color, great controllers Only had one day so far, had to return the first one I bought as it had a line on the right side. BB immediately replaced, and the second works just great. My family has a long history of LG products and their consistent quality.

Rated 1 out of 5 by from Dead pixel on a very nice monitor I bought this monitor 23 days ago, and I saw today that I have a green dot right in the center of the monitor that remains even when cycling through inputs that are not connected eg HDMI2 and DisplayPort, which I interpret as a pixel stuck on green and cannot switch to blue or red or turn off. You can see the green dot in the photo. Power cycling the monitor, changing settings or inputs doesn’t change the fact that there is a green dot permanently in the center of this otherwise nice monitor. Though I have enjoyed it for the last 23 days, I am now out of BestBuy’s 15-day return policy and I must figure out how to get LG to repair it. It probably does not make sense to buy electronics from BestBuy or anyone who doesn’t have a replacement policy for equipment that becomes defective inside of a month. Will not buy electronics from BestBuy ever again. And probably will not buy a LG monitor again.

Rated 3 out of 5 by from Underwhelming panel with a fatal flaw. I purchased this LG 4K IPS monitor for design work and video editing. I put a lot of time into researching the best monitors in this price range and found that this was the best overall panel for the price. There are more expensive LG monitors with the same panel which have more inputs and a nicer stand, but these weren't important to me. However, getting the panel home and plugging it in, I straight away noticed a fatal flaw. Thin lines and text in Windows 10 had a patchy orange/blue glow. The only way I can explain this is to say that where the pixels should have been illuminated white, they were being illuminated blue or orange instead. It's subtle but enough to ruin the monitor for me given the sort of work I needed to do on it. I compared this to two Samsung 1440p PLS panels that I use as well and these didn't have the same issue. Furthermore, the Samsungs had darker blacks (although they are rated for the same contrast ratio and brightness). I tried changing all settings in the panel interface. I also tried changing inputs in the computer, tried a new HDMI cable, re-installed display drivers, changed all display settings in Nvidia control panel, and tried adjusting ClearType settings I ended up returning this for a more expensive Dell 4K monitor which is better in every single way. It doesn't have the same issue rendering thin lines, has darker blacks and better features (albeit at a higher price point). Disappointingly, I had difficulty returning the monitor and had to pay a restocking fee despite the fact that the service technicians at the store could see the same issue I was seeing. They ran tests on the panel and were adament that it wasn't a faulty panel, but that it's just 'how it is'. Have reached out to LG about this but am yet to hear a response (for their benefit not mine, as I've already returned the product).

I purchased the 27UL600-W for photography. The section on setting the GAMMA is vague, Which mode would be equivalent to Gamma 2.20. Also, the Black level control. Does setting it to low, increase the dynamic range.

Asked by: Terrylw64
The Gamma settings for the LG 27'' Class 4K UHD IPS LED Monitor with VESA DisplayHDR 400 (27'' Diagonal), Model # 27UL600-W are given as modes. Based on a gamma value of 2.2, if the square frame appears dark, the monitor's gamma value is low. If the square frame appears bright, the gamma value is high. You can adjust the gamma value by changing the monitor's brightness settings or by adjusting brightness in the driver menu for your graphics card. As the owner's manual advises, "the higher the gamma value, the darker the image becomes. Likewise, the lower the gamma value, the lighter the image becomes"...^IFV
